Bug ID: 63287
Summary: __STDCPP_THREADS__ is not defined
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
16.8 [cpp.predefined] in C++11 says:
__STDCPP_THREADS__
Defined, and has the value integer constant 1, if and only if a program can
have more than one thread of execution (1.10).
I'm not sure what the best way to meet that requirement is, given that . For
some platforms we could make -pthread imply -D__STDCPP_THREADS__, or maybe we
just want to define it unconditionally in every gthr-xxx.h header except
gthr-single.h
